ABSTRACT

Apparatuses, methods, and systems are disclosed for determining a maximum power reduction for non-contiguous radio resource allocations. One apparatus includes a memory comprising instructions executable by a processor to cause the apparatus to determine a non-contiguous resource allocation having a fraction of resource blocks punctured from a smallest containing contiguous allocation (“SCCA”), wherein the SCCA is the smallest set of contiguous resource blocks that encompasses the non-contiguous resource allocation. The instructions are further executable by the processor to cause the apparatus to indicate the non-contiguous resource allocation to a UE and to receive uplink signals on the non-contiguous resource allocation using a first maximum power reduction in response to the fraction of punctured resource blocks being less than a threshold value.

As noted above, the MPR is defined for the UE DFT-s-OFDM UL transmissionin order to enable the UE to meet emissions requirements such as theSpectral Emissions Mask (“SEM”), spurious emissions requirements, andadjacent channel leakage requirements, e.g., UTRA ACLR1, UTRA ACLR2,E-UTRA ACLR, NR ACLR, etc. A-MPR is allowed when additional emissionconstraints are signaled using NS. However, LTE standards do notconsider the situation of a non-contiguous allocation of radioresources.

Disclosed herein are methods, apparatuses, systems, and computer-programproducts for determining a MPR for non-contiguous radio resourceallocations, particularly in a network that uses Cyclic PrefixOrthogonal Frequency Division Multiplexing (“CP-OFDM”). As used herein,a “non-contiguous resource allocation” is defined as a resourceallocation which is not a contiguous resource allocation. Moreover, a“contiguous resource allocation” is defined as a resource allocation ofconsecutive resource blocks within one carrier or across contiguouslyaggregated carriers. Note that the gap between contiguously aggregatedcarriers due to the nominal channel spacing is allowed within thedefinition of a “contiguous resource allocation.”

FIG. 1 depicts a wireless communication system 100 for determining a MPRfor non-contiguous radio resource allocations, according to embodimentsof the disclosure. In one embodiment, the wireless communication system100 includes at least one remote unit 105, a RAN 120, and a mobile corenetwork 140. The RAN 120 and the mobile core network 140 form a mobilecommunication network. The RAN 120 may be composed of a base unit 110with which the remote unit 105 communicates using wireless communicationlinks 115. Even though a specific number of remote units 105, base units110, wireless communication links 115, RANs 120, and mobile corenetworks 140 are depicted in FIG. 1 , one of skill in the art willrecognize that any number of remote units 105, base units 110, wirelesscommunication links 115, RANs 120, and mobile core networks 140 may beincluded in the wireless communication system 100.

In one implementation, the wireless communication system 100 iscompliant with the 5G system specified in the 3GPP specifications. Moregenerally, however, the wireless communication system 100 may implementsome other open or proprietary communication network, for example, LTEor WiMAX, among other networks. The present disclosure is not intendedto be limited to the implementation of any particular wirelesscommunication system architecture or protocol.

In one embodiment, the remote units 105 may include computing devices,such as desktop computers, laptop computers, personal digital assistants(“PDAs”), tablet computers, smart phones, smart televisions (e.g.,televisions connected to the Internet), smart appliances (e.g.,appliances connected to the Internet), set-top boxes, game consoles,security systems (e.g., including security cameras), vehicle on-boardcomputers, network devices (e.g., routers, switches, modems), or thelike. In some embodiments, the remote units 105 include wearabledevices, such as smart watches, fitness bands, optical head-mounteddisplays, or the like. Moreover, the remote units 105 may be referred toas the UEs, subscriber units, mobiles, mobile stations, users,terminals, mobile terminals, fixed terminals, subscriber stations, userterminals, wireless transmit/receive unit (“WTRU”), a device, or byother terminology used in the art.

The remote units 105 may communicate directly with one or more of thebase units 110 in the RAN 120 via UL and downlink (“DL”) communicationsignals. Furthermore, the UL and DL communication signals may be carriedover the wireless communication links 115. Here, the RAN 120 is anintermediate network that provides the remote units 105 with access tothe mobile core network 140. Note that UL transmissions 125 by theremote unit 105 may be subject to a MPR to comply with various emissionsrequirements. Here, the emission requirements vary from one jurisdictionto another.

In some embodiments, the remote units 105 communicate with anapplication server 151 via a network connection with the mobile corenetwork 140. For example, an application 107 (e.g., web browser, mediaclient, telephone/VoIP application) in a remote unit 105 may trigger theremote unit 105 to establish a PDU session (or other data connection)with the mobile core network 140 via the RAN 120. The mobile corenetwork 140 then relays traffic between the remote unit 105 and theapplication server 151 in the packet data network 150 using the PDUsession. Note that the remote unit 105 may establish one or more PDUsessions (or other data connections) with the mobile core network 140.As such, the remote unit 105 may concurrently have at least one PDUsession for communicating with the packet data network 150 and at leastone PDU session for communicating with another data network (not shown).

The base units 110 may be distributed over a geographic region. Incertain embodiments, a base unit 110 may also be referred to as anaccess terminal, an access point, a base, a base station, a Node-B, aneNB, a gNB, a Home Node-B, a relay node, or by any other terminologyused in the art. The base units 110 are generally part of a radio accessnetwork (“RAN”), such as the RAN 120, that may include one or morecontrollers communicably coupled to one or more corresponding base units110. These and other elements of radio access network are notillustrated but are well known generally by those having ordinary skillin the art. The base units 110 connect to the mobile core network 140via the RAN 120.

The base units 110 may serve a number of remote units 105 within aserving area, for example, a cell or a cell sector, via a wirelesscommunication link 115. The base units 110 may communicate directly withone or more of the remote units 105 via communication signals.Generally, the base units 110 transmit DL communication signals to servethe remote units 105 in the time, frequency, and/or spatial domain.Furthermore, the DL communication signals may be carried over thewireless communication links 115. The wireless communication links 115may be any suitable carrier in licensed or unlicensed radio spectrum.The wireless communication links 115 facilitate communication betweenone or more of the remote units 105 and/or one or more of the base units110.

In one embodiment, the mobile core network 140 is a 5G core (“5GC”) orthe evolved packet core (“EPC”), which may be coupled to a packet datanetwork 150, like the Internet and private data networks, among otherdata networks. A remote unit 105 may have a subscription or otheraccount with the mobile core network 140. Each mobile core network 140belongs to a single public land mobile network (“PLMN”). The presentdisclosure is not intended to be limited to the implementation of anyparticular wireless communication system architecture or protocol.

The mobile core network 140 includes several network functions (“NFs”).As depicted, the mobile core network 140 includes multiple user planefunctions (“UPFs”) 145. The mobile core network 140 also includesmultiple control plane functions including, but not limited to, anAccess and Mobility Management Function (“AMF”) 141 that serves the RAN120, a Session Management Function (“SMF”) 143, and a Policy ControlFunction (“PCF”) 147. In certain embodiments, the mobile core network140 may also include an Authentication Server Function (“AUSF”), aUnified Data Management function (“UDM”) 149, a Network RepositoryFunction (“NRF”) (used by the various NFs to discover and communicatewith each other over APIs), or other NFs defined for the 5GC.

Although specific numbers and types of network functions are depicted inFIG. 1 , one of skill in the art will recognize that any number and typeof network functions may be included in the mobile core network 140.Moreover, where the mobile core network 140 is an EPC, the depictednetwork functions may be replaced with appropriate EPC entities, such asan MME, S-GW, P-GW, HSS, and the like. In certain embodiments, themobile core network 140 may include a AAA server.

In various embodiments, the mobile core network 140 supports differenttypes of mobile data connections and different types of network slices,wherein each mobile data connection utilizes a specific network slice.Here, a “network slice” refers to a portion of the mobile core network140 optimized for a certain traffic type or communication service. Incertain embodiments, the various network slices may include separateinstances of network functions, such as the SMF 143 and UPF 145. In someembodiments, the different network slices may share some common networkfunctions, such as the AMF 141. The different network slices are notshown in FIG. 1 for ease of illustration, but their support is assumed.

While FIG. 1 depicts components of a 5G RAN and a 5G core network, thedescribed embodiments for determining a MPR for non-contiguous radioresource allocations apply to other types of communication networks,including Institute of Electrical and Electronics Engineers (“IEEE”)802.11 variants, Universal Mobile Telecommunications System (“UMTS”),LTE variants, CDMA2000, Bluetooth, and the like. For example, in an LTEvariant, the AMF 141 may be mapped to an MME, the SMF 143 may be mappedto a control plane portion of a Packet Data Network Gateway (“PGW”), theUPF 145 may be mapped to a Serving Gateway (“SGW”) and a user planeportion of the PGW, etc.

For LTE, only the DFT-s-OFDM waveform is used for transmission of the ULPhysical Uplink Shared Channel (“PUSCH”). However, in NR (e.g., 3GPP 5GRAT), the UE can transmit the UL using DFT-s-OFDM as in LTE, oralternatively, can transmit using CP-OFDM. In order to meet the ACLRemissions requirement, MPR is to be specified for both DFT-s-OFDM andCP-OFDM.

In various embodiments, the allowed MPR is defined based on a modulationand waveform used for the UL PUSCH. Here, the waveform may be DFT-s-OFDMor CP-OFDM. Examples of modulations include: π/2 BPSK, QPSK, 16 QAM, 64QAM, and 256 QAM. Note that the following parameters may be used tospecify valid RB allocation ranges for Outer and Inner RB allocations:L_(CRBmax), RB_(StartLow), RB_(StartHigh), and RB_(StartInner).

These parameters may be defined as follows: L_(CRBmax) refers to themaximum number of RB for a given Channel bandwidth and sub-carrierspacing derived from spectrum utilization. RB_(StartLow) is equal toL_(CRB)/2 rounded down to next integer with floor at 1. RB_(StartHigh)is equal to L_(CRBmax) - RB_(StartLow) - L_(CRB). RB_(StartInner) refersto valid RB_(START) values for Inner RB allocations.

Here, the Inner RB allocation range is specified as follows: Inner RBallocations are L_(CRB)/2 away from each edge of the maximum RBallocation for all L_(CRB) ≤ L_(CRBmax)/2 rounded up to the nextinteger. For L_(CRB) ≤ L_(CRBmax)/2 rounded up to the next integer,RB_(StartLow) ≤ RB_(StartInner) ≤ RB_(StartHigh). Additionally, theOuter RB allocation range is all allocations which are not Inner RBallocations.

For current 5G systems, MPR is only defined for contiguous RBallocations. Here, the MPR is a function of the waveform type, eitherDFT-s-OFDM or CP-OFDM, and the modulation type which can be PI/2 BPSK,QPSK, 16 QAM, 64 QAM, or 256 QAM.

In 3GPP New Radio (“NR”), a bandwidth part consisting of a group ofcontiguous physical resource blocks (“PRBs”) is used in 3GPP New Radio(“NR”) to support at least: reduced UE bandwidth (“BW”) capability, UEBW adaptation, frequency division multiplexing (“FDM”) of multiplenumerologies (subcarrier spacings), and use of non-contiguous spectrum.Moreover, the use of bandwidth part allows the UE to reduce powerconsumption. It should be noted that bandwidth parts are UE specific andare not restricted to the allowed channel carrier bandwidths in NR, suchas 5, 10, 15, 20, 25, 30, 40, 45, 50, 60, 80, 90, or 100 MHz. It shouldalso be noted that each bandwidth part may have its own Physical UplinkControl Channel (“PUCCH”) resources which can be used for thetransmission of acknowledgements or for the transmission of channelstate feedback, such as Precoding Matrix Indicators, Rank Indicators,and/or Channel Quality Information (“PMI/RI/CQI”).

In some embodiments, a remote unit 105 may use a MPR to meet emissionsrequirements such as the SEM, adjacent channel leakage requirements,UTRA_ACLR1, UTRA _ACLR2, E-UTRA ACLR, NR ACLR, and the spuriousemissions requirements. A-MPR is allowed when additional emissionconstraints are signaled using network signaling.

For example, the remote unit 105 may identify a smallest contiguousallocation containing the non-contiguous allocation and a fraction ofRBs punctured from the smallest containing contiguous allocation, e.g.,due to PUCCH for other remote units 105. Moreover, the remote unit 105may identify a threshold α and determine whether the fraction of RBspunctured from the smallest containing contiguous allocation is lessthan the threshold α. Where the fraction is less than the threshold α,the remote unit 105 may determine an MPR for the non-contiguousallocation, wherein the MPR for the non-contiguous allocation is basedon the MPR for the smallest containing contiguous allocation.

Described herein are UE behaviors for determining a MPR for anon-contiguous resource allocation, particularly for a CP-OFDMallocation in a 5G wireless communication system, such as one compliantwith the 3GPP NR.

FIG. 2 depicts a network architecture 200 comprising a gNB 210 (or othersuitable base station) and multiple UEs, namely a first UE (denoted as“UE1”) 201, a second UE (denoted as “UE2”) 203, and a third UE (denotedas “UE3”) 205. to different UEs, according to various embodiments of thedisclosure. Here, three UEs are being served in the illustratedfrequency band: a first UE 201 having a narrowband allocation 211, asecond UE 203 also having a narrowband allocation 213, and a third UE205 having a wideband allocation 215.

Note that the narrowband allocations 211 and 213 include long PUCCH 220with frequency hopping. Because of the need for the narrowband UE totransmit on its PUCCH even when the narrowband UE is not given an ULPUSCH allocation, it will not in general be possible to allocate acontiguous full-bandwidth block of resources to the wideband third UE205. The PUCCH requirement of narrowband UEs results in puncturedresources 225 in the wideband allocation 215. This puncturing results ina first contiguous part 230 and a second contiguous part 235 in thewideband allocation 215.

Thus, there are two options for the allocation to the third UE 205: thefirst option is to allocate a non-contiguous wideband allocation inwhich the narrowband UE PUCCH resources have been punctured from thethird UE 205′s allocation; the second option is to allocation onlycontiguous RBs (e.g., one of the first contiguous part 230 and thesecond contiguous part 235), however, this will result in a smallerbandwidth allocation. Unless a non-contiguous allowed MPR or A-MPR isdefined for NR CP-OFDM, it is not possible to give the wideband UE anon-contiguous wideband allocation from which the narrowband UE PUCCHresources have been punctured. Accordingly, techniques for definingallowed MPR for non-contiguous allocations are disclosed herein.

One way to define MPR or A-MPR for a non-contiguous allocation is to usethe contiguous MPR (or A-MPR) when the non-contiguous allocation is analmost-contiguous allocation. Here, the assumption is that the number ofpunctured RBs within the otherwise contiguous allocation are limited sothat the normal MPR is sufficient. As used herein, an“almost-contiguous” allocation refers to an allocation where the numberof punctured RBs within the smallest containing contiguous allocationare limited. A non-contiguous allocation may be determined to be an“almost-contiguous” allocation if the amount of punctured resourceblocks meets certain criteria, such as a ratio of punctured RBs to thenumber of RBs in the smallest containing contiguous allocation beingless than a threshold, the size (number) of Punctured RBs being lessthan a threshold, the largest number of contiguously punctured RBs beingless than a threshold, the location of the allocation (e.g., inner orouter) being in a certain location in the carrier/channel, themodulation associated with the allocation being a certain type, thenumber of RBs in the smallest containing contiguous allocation beingwithin a predetermined amount of the channel bandwidth, and othercriteria discussed herein.

In one embodiment, a CP-OFDM allocation is determined to be analmost-contiguous if L_(CRB) of the smallest containing contiguousallocation satisfies L_(CRB) > L_(CRBmax)/ FFS of the given channelbandwidth and the number of resource blocks which are not transmittedwithin the smallest containing contiguous allocation are less than orequal to L_(CRB)/FFS. In such embodiments, the allowed MPR for thealmost-contiguous allocation is that of a contiguous block of RBsstarting and ending with the same RBs as the almost-contiguousallocation.

Above, L_(CRBmax) is intended to mean the maximum number of RBs allowedfor the given channel bandwidth. For a contiguous allocation, L_(CRB) isthe number of allocated RBs. For a non-contiguous allocation, L_(CRB)may be defined to be the number of RBs of the smallest containingcontiguous allocation. As used herein, the “smallest containingcontiguous allocation” refers to a contiguous allocation thatencompasses the non-contiguous allocation. One example of a smallestcontaining contiguous allocation is shown at 240. In certainembodiments, a SCCA is a contiguous allocation having the same startingRBs and ending RBs as the non-contiguous allocation.

FIG. 3 depicts bandwidth parts 300 for different UEs, according tovarious embodiments of the disclosure. Here, the bandwidth parts(“BWPs”) include a first BWP 305 of a first UE (“UE1”), a second BWP 310of a second UE (“UE2”), a third BWP 315 of a third UE (“UE3”), and afourth BWP 320 of a fourth UE (“UE4”). Note that FIG. 3 may be anoversimplified representation of the concept of bandwidth part. BecauseBWPs are UE specific, there is no requirement that BWPs of differentUE’s be aligned.

As depicted in FIG. 3 , the bandwidth parts for different UE’s may havedifferent widths and the boundaries may not be aligned. Furthermore,some bandwidth parts may be fully contained within other bandwidth parts(e.g., the BWPs 310 and 320 are fully contained within the BWP 305).From FIG. 3 , it is apparent that the left PUCCH region for the UE1 andthe UE3 overlap so that the PUCCH resources for these two UEs collide(PUCCH collision 330A), and a similar situation exists for the rightPUCCH region of the UE2 and the UE3 (PUCCH collision 330B). In oneembodiment, this problem may be alleviated by overprovisioning (movinginwards) the PUCCH region, e.g., of the UE2. The point of thisobservation is to note that for bandwidth parts, the PUCCH region maynot be in the edge RBs of the bandwidth part.

In some embodiments, in order for normal MPR to apply, it must be thatL_(CRB) > a portion of the L_(CRBmax) for the given channel bandwidth.In one example, L_(CRBmax) / X for the given channel bandwidth, wherethe value of X is predefined in the wireless network. However, the abovedoes not allow non-contiguous allocations for bandwidth parts containingother bandwidth parts either in whole or in part as is shown in above.

Note that, in FIG. 3 , the bandwidth part for the UE2 is punctured bythe PUCCH region of the bandwidth parts for the UE3 and UE4. Similarly,the bandwidth part for the UE3 is punctured by the PUCCH region ofbandwidth part for the UE2. Thus, for the more general cases illustratedin FIG. 3 , it may not be desirable to require that L_(CRB) > L_(CRBmax)/ X, as with this requirement, it may not be possible to allownon-contiguous allocations for smaller bandwidth parts.

Because different emissions constraints limit the transmit power (andthus determine the needed MPR), it will in general be true that agreater fraction of RBs can be punctured from the contiguous RBallocations located in some parts of the table of 3GPP TS 38.101 whilestill meeting emissions requirements, than can be punctured from thecontiguous RB allocations located in other parts of the table.

In various embodiments, the UE 205 may support non-contiguous MPR forCP-OFDM based on the MPR for the smallest contiguous allocationcontaining the non-contiguous allocation. For a non-contiguousallocation of span L_(CRB), let L_(CRB) denote the number of RBs in thesmallest contiguous allocation containing the non-contiguous allocation.

MPR is defined for the non-contiguous allocation if the fraction of RBspunctured from the smallest containing contiguous allocation is lessthan a threshold α which is strictly less than 1. Let N_(RB_) _(GAP)represent the number of unallocated RBs between allocated RBs (e.g., thenumber of punctured RBs) and let N_(RB_) _(ALLOC) is number of allocatedRBs. The non-contiguous allocation may be considered analmost-contiguous allocation, and have a defined allowed MPR, if thefollowing is satisfied:

N_(RB_GAP)/(N_(RB_ALLOC) + N_(RB_GAP)) ≤ α

Note that that quantity “N_(RB_GAP) + N_(RB_) _(ALLOC)” represents thenumber of RBs in the SCCA. Accordingly, the SCCA may be defined asfollows:

N_(SCCA) = N_(RB_ALLOC) + N_(RB_GAP)

In certain embodiments, Equation 1 may apply only if the size of theSCCA as above a minimum amount. Here, the minimum amount may be based onthe subcarrier spacing of the non-contiguous allocation. In oneembodiment, threshold α be 0.25 or less. In certain embodiments, thevalue of α may depend on whether the smallest containing contiguousallocation is an inner allocation or an outer allocation. In someembodiments, the threshold α may depend on the modulation of thenon-contiguous allocation, e.g., QPSK, 16QAM, 64QAM, 256 QAM.

In certain embodiments, the value of α may depend on the centerfrequency of the carrier, F_(c). In certain embodiments, the value of αmay depend on L_(CRB). In certain embodiments, the value of α may dependon the lowest index RB, RB_(START). In certain embodiments, the value ofα may depend on the NS value signaled.

Note that for some contiguous allocations, MPR may not be defined forany non-contiguous allocation resulting from puncturing the contiguousallocation. For example, if the SCCA is located in certain portions ofthe frequency band, then MPR may not be defined for the non-contiguousallocation. In one embodiment, the MPR is defined based on a starting(e.g., lowest) or ending (e.g., highest) resource block index of theallocation.

In various embodiments, the allowed MPR for the non-contiguousallocation may be allowed to increase by a value β dB relative to theallowed MPR for the SCCA. Here, the value β may be as large as thenegative of 10 times the base 10 logarithm of the fraction of theL_(CRB) RBs punctured. Here, the value of β is based on the ratio of RBspunctured. In certain embodiments, the value of β may be defined using aceiling function to map the fraction of RBs punctured from the smallestcontaining contiguous allocation to a decibel value in steps of 0.5 dBas follows:

β=⌈10 log₁₀(1 + N_(RB_GAP)/N_(RB_ALLOC)), 0.5⌉dB

FIG. 4 depicts one embodiment of a user equipment apparatus 400 that maybe used for determining a MPR for non-contiguous radio resourceallocations. In various embodiments, the user equipment apparatus isused to implement one or more of the solutions described herein. Theuser equipment apparatus 400 may be one embodiment of the remote unit105. Furthermore, the user equipment apparatus 400 may include aprocessor 405, a memory 410, an input device 415, an output device 420,and a transceiver 425.

In some embodiments, the input device 415 and the output device 420 arecombined into a single device, such as a touchscreen. In certainembodiments, the user equipment apparatus 400 may not include any inputdevice 415 and/or output device 420. In various embodiments, the userequipment apparatus 400 may include one or more of: the processor 405,the memory 410, and the transceiver 425, and may not include the inputdevice 415 and/or the output device 420.

As depicted, the transceiver 425 includes at least one transmitter 430and at least one receiver 435. In some embodiments, the transceiver 425communicates with one or more cells (or wireless coverage areas)supported by one or more base units 121. In various embodiments, thetransceiver 425 is operable on unlicensed spectrum. Moreover, thetransceiver 425 may include multiple UE panels supporting one or morebeams. Additionally, the transceiver 425 may support at least onenetwork interface 440 and/or application interface 445. The applicationinterface(s) 445 may support one or more APIs. The network interface(s)440 may support 3GPP reference points, such as Uu, N1, PC5, etc. Othernetwork interfaces 440 may be supported, as understood by one ofordinary skill in the art.

The processor 405, in one embodiment, may include any known controllercapable of executing computer-readable instructions and/or capable ofperforming logical operations. For example, the processor 405 may be amicrocontroller, a microprocessor, a central processing unit (“CPU”), agraphics processing unit (“GPU”), an auxiliary processing unit, a fieldprogrammable gate array (“FPGA”), or similar programmable controller. Insome embodiments, the processor 405 executes instructions stored in thememory 410 to perform the methods and routines described herein. Theprocessor 405 is communicatively coupled to the memory 410, the inputdevice 415, the output device 420, and the transceiver 425.

In some embodiments, the transceiver 425 receives a non-contiguousresource allocation, e.g., from a gNB 210 in a wireless communicationsystem. The gNB 210 may be one embodiment of the base unit 110,described above. Moreover, the processor 405 is configured to identifythe non-contiguous resource allocation. In certain embodiments, thenon-contiguous resource allocation contains a plurality of smallercontiguous resource allocations. Here, the non-contiguous resourceallocation is contained within a SCCA, such that the SCCA is defined asthat smallest set of contiguous resource blocks that encompasses thenon-contiguous resource allocation.

The processor 405 determines a MPR for the non-contiguous resourceallocation based on whether a fraction of resource blocks punctured fromthe SCCA is less than a threshold α. Here, the value of α (alpha) may bepredetermined or configured by the gNB 210. In various embodiments, theallowed MPR for the non-contiguous resource allocation is based on theallowed MPR for the SCCA. In various embodiments, the SCCA is a set ofcontiguous resource block that encompasses the non-contiguous resourceallocation, wherein the non-contiguous resource allocation contains aplurality of smaller contiguous resource allocations.

In some embodiments, determining the MPR for the non-contiguous resourceallocation includes selecting an allowed MPR defined for the SCCA inresponse to the fraction of resource blocks punctured from the SCCAbeing less than a threshold α. In further embodiments, determining theMPR for the non-contiguous resource allocation includes increasing aselected MPR for the SCCA by a value β (beta). In one embodiment, thevalue β is a function of the fraction of resource blocks punctured fromthe SCCA. In further embodiments, the value β is the negative of 10times the base 10 logarithm of the fraction of resource blocks puncturedfrom the SCCA.

However, the processor 405 may determine that no MPR is defined for thenon-contiguous allocation if the fraction of resource blocks puncturedfrom the SCCA is not less than the threshold value. Alternatively, theprocessor 405 may determine that the MPR of the non-contiguousallocation does not depend on the allowed MPR of the SCCA if thefraction of resource blocks punctured from the SCCA is not less than thethreshold value. In such embodiments, the allowed MPR of thenon-contiguous allocation may be determined using a lookup table, bynetwork signaling, or the like.

In some embodiments, the transceiver 425 receives, from the wirelesscommunication system, an indication of additional emission requirements,such that an additional MPR (e.g., A-MPR) is allowed. Here, the MPR(e.g., total MPR) for the non-contiguous resource allocation is furtherbased on the indication. In various embodiments, the indication ofadditional emission requirements is received by NS signaling, forexample by the gNB 210 sending a NS value.

In certain embodiments, the threshold α is based on the lowest resourceblock index of the allocation. In certain embodiments, the threshold αis based on a number of resource blocks in the SCCA. In certainembodiments, the threshold α is based on a center frequency of a carrierto which the non-contiguous resource allocation belongs. In certainembodiments, the threshold α is based on a modulation of thenon-contiguous resource allocation.

Moreover, the processor 405 controls the transceiver 425 to transmit atleast one UL signal on the non-contiguous resource allocation using thedetermined MPR. In certain embodiments, transmitting the UL signal(s) onthe non-contiguous resource allocation using the MPR includestransmitting the UL signal(s) using a CP-OFDM waveform.

The transceiver 425 communicates with one or more network functions of amobile communication network via one or more access networks. Thetransceiver 425 operates under the control of the processor 405 totransmit messages, data, and other signals and also to receive messages,data, and other signals.

In some embodiments, the first transmitter/receiver pair andthe second transmitter/receiver pair may share one or more hardwarecomponents. For example, certain transceivers 425, transmitters 430, andreceivers 435 may be implemented as physically separate components thataccess a shared hardware resource and/or software resource, such as forexample, the network interface 440.

In various embodiments, one or more transmitters 430 and/or one or morereceivers 435 may be implemented and/or integrated into a singlehardware component, such as a multi-transceiver chip, asystem-on-a-chip, an Application-Specific Integrated Circuit (“ASIC”),or other type of hardware component.

Further, thetransmitter(s) 630 and the receiver(s) 635 may be any suitable type oftransmitters and receivers.

FIG. 7A depicts one example of a table 700 of A-MPR for a non-contiguousresource allocation. Here, the A-MPR values are used for the case thatthere are additional emissions restrictions in addition to the normalrestrictions on the SEM, ACLR limits, in-band emissions limits, andspurious emissions limits. For the case of additional emissionsrestrictions, the gNB 210 send an indication of the additional emissionsrestrictions (e.g., an indication of an additional power reduction) tothe UE. These additional restrictions may be indicated by NS, e.g., bysending a NS value. The UE then determines the A-MPR and the allowed MPRbased on the determined A-MPR. In certain embodiments, the determinedA-MPR is added to the (normal) allowed MPR for the non-contiguousallocation to arrive at the total MPR. The UE then uses the total MPRwhen transmitting signals in the network.

For contiguous allocations, MPR for CP-OFDM with contiguous allocationswill be specified in the form of table similar to that of Table 700.Here, Table 700 may apply when the network entity (e.g., gNB or otherRAN node) signals the value “NS_07”. From Table 700, it can be seen thatMPR for a contiguous allocation depends on RB_(START), the location ofthe first RB of the contiguous allocation, and L_(CRB), the number ofRBs in the contiguous allocation. In certain embodiments, the A-MPRvalue may be adjusted by the value β discussed above.

Note that in the Table 700, the parameter ‘RB_(START)’ indicates thelowest RB index of transmitted resource blocks and the parameter‘L_(CRB)’ is the length of a contiguous resource block allocation. Notethat for intra-subframe frequency hopping which intersects regions, theparameter ‘RB_(START)’ and the parameter ‘L_(CRB)’ apply on a per slotbasis. Additionally, for intra-subframe frequency hopping whichintersects regions, the larger A-MPR value may be applied for both slotsin the subframe.

FIG. 7B depicts another example of a table 750 of A-MPR for anon-contiguous resource allocation, here associated with a different NSvalue. In various embodiments, the table 750 may apply when a value of“NS_04” signaled. In the table 750, it can be seen that the MPR dependson RB_(START) and L_(CRB), as in the example above, but also depends onthe center frequency of the carrier, F_(c).

Note that in the Table 750, the parameter ‘RB_(START)’ indicates thelowest RB index of transmitted resource blocks and the parameter‘L_(CRB)’ is the length of a contiguous resource block allocation. Notethat for intra-subframe frequency hopping which intersects regions, theparameter ‘RB_(START)’ and the parameter ‘L_(CRB)’ apply on a per slotbasis. Additionally, for intra-subframe frequency hopping whichintersects regions, the larger A-MPR value may be applied for both slotsin the subframe.

Moreover, for NR with CP-OFDM modulation, the MPR tables for contiguousallocations with additional emissions restrictions (indicated using NSsignaling) may also depend on the parameters RB_(START), L_(CRB), andF_(c), in addition to the modulation order.

When NS-signaled additional emissions constraints are used with CP-OFDMmodulation, the existing MPR table defined for general emissionsrequirements may not be sufficient to meet these requirements. Thus,when additional emission requirements are signaled, it may be necessaryto define additional MPR tables for CP-OFDM that depend on RB_(START),L_(CRB), and F_(c), in addition to the modulation order. Examples, ofsuch tables are depicted above, in Tables 700 and 750. From these tablesdefining MPR for CP-OFDM with additional emissions constraints, it willalso be necessary to define MPR for non-contiguous allocations due tothe need to puncture out the PUCCH region of bandwidth parts which liewithin the full channel bandwidth as shown in FIG. 3 .

It can be noted that in different regions of these tables, differentemissions constraints may limit the power that can be transmitted andthus determine the required MPR. For example, for higher ordermodulations such as 64-QAM, it may be that in-band emissionsrequirements are the gating factor on the amount of power that can betransmitted. Conversely for large allocations, the ACLR requirements maylimit the transmit power. Thus, in different regions of the table, itmay be possible to puncture a smaller or larger number of RBs and stillmeet emissions requirements. Thus, the fraction of RBs α that can bepunctured from the allocation while still meeting emissions requirementswill depend on the region of the table as determined by the parametersRB_(START), L_(CRB), and F_(c), in addition to the modulation order. Anon-contiguous allocation has a span of L_(CRB), where L_(CRB) is thenumber of RBs in the smallest contiguous allocation containing thenon-contiguous allocation.

FIG. 8 is a flowchart diagram of a method 800 for determining an MPR fora non-contiguous allocation.
